I too started with Linux at 14. I just got my first computer, an old laptop with Windows. It was too slow and I couldn't even figure out anything in settings. (Windows 10 and its Settings + reduced Control Panel).

I at first tried to find "Linux". I had little idea about it, but I thought Linux must be it, and these others were just modifications, so I kept trying to find "pure Linux". Eventually figured out the distributions thing and decided on Mint (MATE).
I dug through all old movies just to find a rarity. One single movie burned to DVD-RW, perfect! (First computer, why would I have a USB drive?)

In the end I was using Windows for whopping 2 days.

And since I finally had a proper computer, it only took a few months and my phone was running a custom ROM (PixelExperience).
